HANS PAULSON, OF ORTING, WASHINGTON.

MANURE-CONVEYER.

To all whom it may concern:

Be it known that I, HANS PAULSON, a citizen of the United States, residing at Orting, in the county of Pierce and State of WVashington, have invented a new and useful Manure-Conveyer, of which the followin is a specification.

lIy invention relates to improvements in manure conveyers and has for its objects to provide a car adapted for use in farms and stables for the removal of manure without the necessity of handling it after it is placed therein. I attain this and other objects by the devices, mechanisms and arrangements illustrated in the accompanying drawings, in which-- Figure 1 is a side elevation, partly in section, showing my device as applied in a barn; Fig. 2 is a side elevation of a lower corner of the dump car showing the springactuated bottom; Fig. 3 is a front elevation thereof; Fig. 1 is a side view of the dump car; Fig. 5 is a front View thereof, showing a portion thereof in section and showing the supporting floor of the barn in section; and Fig. 6 is a vertical longitudinal section of the front end of the car showing also the trip bar.

Similar numerals of reference refer to similar parts throughout the several views.

In the floor of the barn is constructed a long trough 1, preferably slightly inclined, at suitable intervals in the bottom of which are made the trap doors 2, preferably opening upward. Below the floor and on each side of the trough 1 are hung the supporting rails 3 which consist of flat bars having their edges uppermost and supported by means of .rods 4 suitably secured to the floor or its joists. These rails 3 are parallel and lie in the same plane throughout their length but are preferably inclined slightly downward in the direction in which the loaded car is to be transported. Outside of the barn these rails may be supported by any suitable device from the ground, such as by means of suitable bridge work, according to their length and elevation from the ground. A trip-bar 5 is adjustably secured to the two rails 3 at the point at which it is desired that the car be dumped, said bar hanging down below the rails and extending therebetween.

The car consists of a four-sided body, preferably made of sheet metal, and has an angle-iron 6 secured around its sides 7 at a level just below the lower edge of the sup- Specification of Letters Patent.

porting rails 3, saidangle-iron extending out sutficiently far from the said sides and under the said rails thus preventing the car from jumping the track when unevenly loaded or when being moved on the track. The car is supported on the rails 3 by means of double flanged wheels 8, supported outside of the ear between the upper edges of the sides 7 and suitable brackets 9 secured to the said sides. These wheels 8 rest on the rails 3. Suitable brackets 10 extend vertically downward from the two opposite sides of the car below the lower edge thereof and support therein the two pivot shafts 11 which run lengthwise of the car on each side thereof. To these shafts 11 are suitably secured the bottom levers 12, to the upper sides of which are secured the bottom plates 13 of the car. These plates 13 extend from under the sides of the car to the middle thereof. The front ends of the pivot shafts 11 are bent at right angles toward the center of the car and have their ends 14 suitably shaped (Fig. 6) to engage the notched latch bars 15. These latch bars 15 are pivoted at 16 between two brackets 17, secured to the front end of the car, and are pressed outward from the car by means of springs 18, adapted to prevent their becoming accidentally disengaged from the ends 14.- of the shafts 11. The latch bars prevent the shafts from turning under the load on the bottom plates.

The position of the latch bars 15 is such that when the car reaches the dumping point they will engage the trip-bar 5 and the motion and momentum of the car will compress the springs 18 thus releasing the ends 14 of the pivot shafts 11. The result is the weight within the car will turn the bottom plates 13 thereof downward, with the pivot shafts 11, thus dumping the contents thereof. In order to return the plates to their normal position as soon as the load is dumped, I either provide aweight 19 (Figs. 4; and 5) secured thereto on an arm in such position that the weight will always tend to close the said plates, or I provide a spring 20 (Figs. 2 and 3) engaging the car and the bottom plates and wound around the pivot shafts 11 in such a manner as to tend to close the said plates.

The car is drawn along the tracks by any suitable means; I have illustrated, however, a cable 21 secured to the two ends thereof and passing around suitable idler wheels 22 at the ends of its travel, said cable preferably returning above the floor of the barn in such position as to be within reach from the floor thereof so that the car can be pulled from place to place by the attendants in the barn.

Having described my invention, what I claim is 1. In a manure conveyer, the combination of a supporting track; a four-sided car supported by said track and movable thereon; pivot shafts supported on two longitudinal sides of said car; bottom plates secured to said pivot shafts; latch levers engaging said pivot shafts to prevent their turning,

. and supporting said bottom plates in closed position; and a trip-bar adjustably secured to said track and adapted to engage said latch levers to disengage them from the pivot shafts, whereby said pivot shafts are allowed to turn and to remove said bottom plates from under the car.

2. In a manure conveyer, the combination of a supporting track; a four-sided car; double-flanged wheels mounted on the up per sides of said car and engaging said track whereby said car is supported by the track and is movable thereon; a flange secured to said car and extending beneath said track; pivot shafts supported on two longitudinal sides of said car; bottom plates secured to said pivot shafts; spring actuated latch levers engaging said pivot shafts to prevent their turning, and supporting said bottom plates in closed position; a trap bar adjustably secured to said track and adapted to engage said latch levers to disengage them from the pivot shafts, whereby said pivot shafts are allowed to turn and to remove said bottom plates from under the car; and means for returning said bottom plates to their closed positions.

3. In a manure conveyer, the combination of a supporting track; a four-sided car; double-flanged wheels mounted on the upper sides of said car and engaging said track whereby said car is supported by the track and is movable thereon; a flange secured to said car and extending beneath said track; pivot shafts supported on two longitudinal sides of said car; bottom plates secured to said pivot shafts; spring actuated latch levers engaging said pivot shafts to prevent their turning, and supporting said bottom plates in closed position; a trip bar adj ustably secured to said track and adapted to engage said latch levers to disengage them from the pivot shafts, whereby said pivot shafts are allowed to turn and to remove said bottom plates from under the car; means for returning said bottom plates to their closed positions when the load is removed therefrom; and means for actuating said car along the track. 7
